If you don't use any equipment, how do you get your cardio workout in? I live in a cold climate, so doing things outside is not an option with two little ones.
I use the Wii Fit and do their yoga workouts and then run in place to the tv during free run. It definitely isn't as high impact as running on a treadmill or around the track, but it is something.

Use DVDs.
Taebo is an awesome work out.
